Collagen

What is Collagen?

Collagen is the most abundant protein in the human body, making up nearly one-third of its total protein content. It serves as the main structural component of connective tissues, including skin, bones, tendons, ligaments, and cartilage. Think of collagen as the scaffolding that holds the body together—providing structure, strength, and elasticity across multiple systems. Without it, tissues would lack firmness, flexibility, and resilience. There are over two dozen types of collagen, but Types I, II, and III are the most significant when it comes to beauty and wellness. Type I collagen is the most prevalent and is found in skin, bones, tendons, and ligaments. It plays a critical role in keeping skin firm and smooth while maintaining bone density and muscle structure. Type II collagen is found primarily in cartilage and supports joint flexibility and cushioning. Type III works alongside Type I in the skin and blood vessels, promoting elasticity and circulation. As we age, collagen production naturally slows down. Beginning in our mid-20s, the body produces less collagen each year, leading to visible signs of aging such as fine lines, wrinkles, sagging skin, brittle nails, and joint stiffness. Environmental stressors like UV exposure, poor diet, and pollution can further accelerate this decline.

To counteract these effects, many people turn to collagen supplementation. Most supplements today use hydrolyzed collagen, also known as collagen peptides. These are collagen molecules broken down into smaller amino acid chains, allowing for easier absorption by the body. Once absorbed, collagen peptides stimulate the body’s own collagen-making processes while also supplying the raw materials needed to rebuild connective tissue. The benefits of collagen go far beyond the surface. Regular use of collagen supplements has been shown to enhance skin hydration, improve elasticity, and reduce the depth of wrinkles. It also supports hair and nail strength, reducing breakage and promoting growth. These visible improvements make collagen a staple in beauty-focused products and routines. Collagen is equally important for internal health. It helps preserve joint mobility by maintaining the integrity of cartilage, reducing joint pain, and supporting flexibility. Athletes and active individuals often use collagen to promote muscle recovery and reduce the risk of injury. Some collagen supplements are combined with Vitamin C, hyaluronic acid, or MSM (methylsulfonylmethane) to further boost their effectiveness, especially for skin and joint care. Different sources of collagen offer unique advantages. Bovine collagen, derived from cows, is rich in Types I and III. Marine collagen, sourced from fish, is highly bioavailable due to its small peptide size and is popular for its sustainability and suitability for pescatarians. Chicken and porcine collagens are also commonly used, especially in joint-focused formulas.

Overall, collagen is a foundational protein that supports the structure and health of the entire body. Whether your goal is to maintain youthful skin, support joint comfort, or reinforce hair and nail strength, collagen supplementation offers a well-researched and accessible way to promote long-term health and resilience.
